The term ‘Anthropocene’ was coined in recognition that human activities have ended the relatively stable environment of the Holocene epoch. However, its widespread adoption across the humanities, arts and sciences has led to diverse and sometimes incompatible definitions. In this Perspective, we argue for a stabilized definition of the Anthropocene epoch to help address contemporary environmental challenges, and explore various applications of the Anthropocene across disciplines. The Anthropocene epoch, with a proposed start point in 1952, underscores that human-driven global-scale environmental disruption differs from earlier human impacts of the Holocene, which did not cause such profound destabilization. This clear distinction enables quantitative and qualitative comparisons between the Holocene and Anthropocene epochs, as already utilized, for instance, within the planetary boundaries framework. As the Anthropocene Earth system transformation is systemic, political responses also need be systemic, rather
En avril dernier, une édition augmentée et mise à jour de l’ouvrage « Carbone fossile, carbone vivant » a été publiée chez Folio. Cet ouvrage pédagogique, dont nous vous recommandons vivement la lecture, permet de découvrir et de mieux comprendre de nombreuses problématiques liées à l’énergie et au climat. Nous avons interrogé son auteur, Christian de Perthuis, économiste du climat.
The concepts of Green Growth and Degrowth represent two major narratives in the public and academic debate on socio-ecological transformation. . . Using a comparative analysis of the two research fields, we confirm several findings from previous reviews, including that Green Growth research is highly policy oriented, focuses on practical implementation and builds on empirical research methods, while Degrowth research is highly theory-driven, focuses on the analysis of complex human-nature interrelationships and builds on a sound theoretical and conceptual foundation. Our analysis further reveals that Green Growth and Degrowth are two rather isolated fields of research with little exchange and mutual reference on related topics. However, the topic of social change and transition represents an intersecting and promising future research area. . . .
Les adeptes du mouvement Hardal, mélange de fondamentalisme religieux et d’ultranationalisme, investissent l’institution militaire. Leur discours déshumanisant à l’égard des Palestiniens a contribué à l’anéantissement de la bande de Gaza.
La production alimentaire et les combustibles fossiles causent 5 milliards de dollars de dégâts environnementaux par heure Un rapport du PNUE affirme que mettre fin à ces dommages est essentiel à la transformation mondiale nécessaire « avant que l’effondrement ne devienne inévitable ».
What if the real danger wasn’t the crises ahead… but the established illusion that we can solve them without changing the system that produces said crises? In this uncompromising and deeply eye-opening talk, renowned systems thinker and strategist Arthur Keller challenges one of the most comforting ideas of our time: the belief that “solutions exist” to the great planetary predicaments of our time. Climate action, energy transition, technical innovation… are all crucial, yet they’re somewhat off topic if they remain integrated within a system that inexorably turns nature into waste. Arthur reframes the situation with brutal clarity. Humanity is not facing an ecological crisis: it is nature that’s facing a human crisis. The problematic is no collection of isolated problems to tackle one by one: it is rather the symptom of a civilization operating beyond planetary limits. Decarbonizing energy without transforming the underlying system, he argues, is like treating cancer with painkillers. The disease keeps sprea
L’agriculture représente près d’un quart du PIB du pays et emploie un Brésilien sur cinq. Un décollage amorcé il y a quarante ans et qui repose en grande partie sur le développement des OGM et la transformation des sols.

UN GEO report says ending this harm key to global transformation required ‘before collapse becomes inevitable’
Le rapport GEO-7 du PNUE, élaboré par 287 scientifiques de 82 pays, plaide pour des transformations radicales de l'économie mondiale, jugeant le coût de l'inaction supérieur aux investissements nécessaires.
Souvent présenté comme un levier indispensable pour décarboner nos économies, le numérique est loin d’être une solution miracle. Derrière ses promesses techniques et économiques se cachent des coûts environnementaux et humains croissants. La planète ne bénéficiera pas nécessairement d’une numérisation massive qui risque, au contraire, d’aggraver notre dépendance en termes de et d’énergie.
